In meteorology, a tropical cyclone is a storm system fueled by the heat released when moist air rises and condenses. The name underscores their origin in the tropics and their cyclonic nature, which is that its circulation is counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. They are distinguished from other cyclonic windstorms such as nor'easters, European windstorms, and polar lows by the heat mechanism that fuels them, which makes them "warm core" storm systems.
Depending on their location and strength, there are various terms by which tropical cyclones are known, such as hurricane, typhoon, tropical storm, cyclonic storm and tropical depression.
Tropical cyclones can produce extremely strong winds, tornadoes, torrential rain, and huge waves swamping coastal areas called storm surges. The heavy rains and storm surges create giant floods. Although the effects on human populations can be catastrophic, tropical cyclones have also been known to relieve drought conditions because they transport enormous amounts of moisture. They carry heat away from the tropics, an important mechanism of the global atmospheric circulation that maintains equilibrium in the earth's troposphere.
